tains to make and use the same.

My invention relates to improvements in rail spiking machines adaptedfor spiking ties in rapid succession.

An important object ofthis invention is to provide aspik'e drivingmachine having novel means for supporting the spikes prior to and whilebeing driven into the tie.

A further object is to provide a spike driving machine having means forspacing the spike holding members on opposite sides of the rails whenpassing the fish plates or other lateral projections.

A further object is to provide means for supporting and operating thedriving members whereby the spikes on one or both sides of the tie maybe driven home separately or simultaneously.

A further object is to provide a spike driving machine having means foradjustably and rigidly supporting the spike driving hammers whereby thesame may be readily adjusted for spiking difl'erent width rails.

A further object is to provide a rail spiking machine which is of highlysimplified construction, durable in use and which may be operated with aminimum of'attendant labor.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

Fig. 8 is a fragmentary sectional view on line through theupper portionof one of the cyl-. ll'lClGIS, the view illustrating the exhaust port ofthesame, and

In the drawings wherein for the purpose of illustration is shown thepreferred embodiment of my invention, the numeral 10 designates a truckor car rotatably mounted The wheels operate on a track including rails12 and ties 13. A hammer supporting and operating structure generallydesignated by the numeral 1 1 is mounted at one end of the truck andincludes independently operated members arranged above each rail. Eachham-v mer supporting and operating structure includes a pair of spacedvertical guides-.15

having attaching brackets 16 extended therefrom and secured to the truckor car by bolts reciprocatory piston 18 is mounted within the cylinder16 and is provided with a vertical depending piston rod 19 havingconnection with a head 20 slidably mounted between the guides 15.

As indicatedin Fig. 2 the vertical edge portions21 of the guides 15extend about the front andrear edges of the head 20 and thereby preventundue movement of the head.

A valve chest 22 is carried by the cylinder 16 and is provided withavalve 23 adapted for supplying fluid pressure to both sides of thepiston whereby the same may-be elevated and lowered as desired, .A manually controlled lever 24 has connection with the valve and is adaptedfor controlling the position of the same. -A segmental rack 25 carriedby the valve chest is adapted to be engaged by a dog 26 carried by thelever 24 for locking the lever in an adjusted position. A fluid pressuresupply pipe 27 is adapted for supplying fluid pressure to the valvechest from where. it is conveyedto either side of the cylinder. A'pair.of coil of the guides and are disposed on opposite sides of the pistonrod 19 for cushioning.

7 one of their sides inclined outwardly as indicated at 33'forcontacting with the inclined sides 31 of the grooves. The top of thehammers flatly abut the top walls of the grooves, whereby uponengaging'the spikes the full force of theimpact will be transmitted tothe heads. Theincline'd sides 31 and prevent the loosening of thehammers i strain.

within the grooves as the result of lateral Transversely extendingadjusting screws 3i have'threaded engagement with .the upper portions 32of the hammers and are adapted to be rotated for adjusting the hammerslaterally. The heads 35 of each bolt are mounted within oval shapedrecesses 36 in the head. Annular shoulders 37 are formed on the screwbolt 34 at points spaced from the heads 35 and form annular recesses inwhich retaining washers 38 are partially received for preventinglbn'gitudi na l movement of the screw bolts. The retaining washers 38are held in position by locking screws 39. Set screws 40 have threadedengagement with the sides of the heads and engage the sides of thehammers forlocking the same in adjusted position and have their headsmounted iii-recesses 41.

Spike supporting members generally designated by the numeral 42' areclearly shown in'Figs. 6 and 7' and are arranged on each side of therails one'slightly in advance of the other. Eac'h'spike supporti-ngmember inchldes a pair of casings 43' arranged in endwise relation andhaving their adjacent ends open for the reception of the shank portions43-3 ofj'aw's' la. The casings are rigidly connected by anrintennediateplate 4A5 which is oflsetat its" endsto dispose its centralportionoutwardly Plates 46 are detachably secured to the inner sides of thecasings 43 by bolts 4'7. The jaws are settog'ether by coil s rings 48arranged within the casing and are limited in their forward movement bytransverse stops: or bolts '49 extending through elongated slots 50provided in the shank portions 43' of the jaws. Thej aws areprovidedadjacent their spike engaging ends with inwardlyiexten'ding offsets 51which d-isposethe' spike-engaging portions 52 directly'below'the-hammers.

The adjacent ends of the jaws are provided with recesses. formingopenings in which the spikes 53 are received. The upper faces 54 of theadjacent end portions of the jaws are inclined downwardly to serve asguides for the spikes and also to be squarely engaged by the inclinedlower end portions 55 of the hammers which serve to push the jawsoutwardly upon engaging the same.

The spike supporting members suspended from arms 56 having attachingplates 57 secured to the connecting plates 45 by bolts 58. The upperends of the" arms are; provided with inwardly directed sleeves-59provided with rectangular openings slidablyr eceiving'a uared shaft 60.The shaft 60 is suspended rom brackets 61 secured to the truck by bolts62. v Collars 63 are mounted on the squared shaft 60' and are adaptedfor limiting the inwardmovement of the sleeves 59'. Set screws 64securely retain the collars in a set position.

Apertured ears 65 are" carried by the sleeves59 and are connected to theends of a contractile coil spring 66 adapted for re taining the sleevesin contact with the col-- lars 63' whereby the spike supporting membersare normally retained in their" innermost positions.

Links 6? are pivotally connected to the sides of the sleeves and havetheir upper ends pivotally connected to a vertically movable pedal 63which is extended through the bottom of the truck and guide plates 69. Apivoted level 70 is arranged in contact with the upper portion ot thepedal and is adapted to be operated fordepressing the same. Upon thespike supporting members approaching the fish plates of the rails orother lateral projections, the pedal 68 may be depressed and the pairsofspike engaging members thereby caused to separate-. Immediately uponremoving the pressure from the pedal 68, the spike supporting membersassume their normal inward position di'rectlybel'o'w the hammers. Spikesupplying tubes 7O are carried by the truck and adapted for supplyingthe spikes to the recesseswithin the jaws. The spikes are fed manuallytothe tubes as each tie is aboutto bespike'd. As illustrated in Fig.S'the lower portion of each spike supplying tube is provided with ahinged section 71 adapted to be swung outwardly'upon being engaged bythe head. 20 on itsdoe nward movem'ent. Shoulders 72 are carried by theadjacent ends of the spout 70 and the section -71 and serve to limit theinward swinging movement of the section 71. Arms 73 extend ing inwardlyfrom the section 71- and the spout 70 are connected'byacoil spring 74which serves to normally retain the section 71 in arlinement with thespout;

In: operation the spike driving. and supporting mechanism is arrangeddirectly spike driving operating, the fluid pressure supply, is reversedand the fluid pressure supplied to .the under side of the pistonswhereby the hammers are elevated, preparatory to spiking the next tie.

While I have shown and described the preferred embodiment ofmy'invention, it

is understood that such minor changes in arrangement andconstruction ofparts may be made as Wlll remain within the spirit of the invention andthe scope of. the appended claims.
